The LM2500+G4 SAC 50Hz Combined Cycle 2x1 is a high-performance gas turbine system designed for large-scale, high-efficiency power generation, particularly suited to the needs of oil and gas operations. This configuration links two LM2500+G4 gas turbines with a single steam turbine in a combined cycle layout—capturing waste heat from the gas turbines to produce steam and generate additional power. This approach significantly improves overall thermal efficiency while maintaining operational flexibility.

The Single Annular Combustor (SAC) with optional water injection helps the system meet emissions rules while keeping combustion stable and efficient. The LM2500+G4 improves on the previous +G4 model by increasing airflow, using better materials, and adding improved cooling. This allows it to produce about 10% more power without reducing the lifespan of critical hot parts. It can be equipped with either a two-stage or six-stage power turbine to fit different needs. Even with the higher power output, the +G4 keeps its modular, two-spool design, which makes maintenance easier and ensures reliable performance in many environments.

In the 2x1 configuration, the system delivers approximately 41% more power than a single gas turbine unit. The use of combined cycle technology ensures better fuel utilization, helping to reduce overall emissions and lower lifecycle operating costs.

The LM2500+G4 SAC 50Hz Combined Cycle 2x1 offers higher power, improved efficiency, and a flexible design, making it well-suited for large-scale oil and gas operations that demand reliable and efficient power generation. Its “50Hz” designation means the turbine is specifically optimized to supply electricity to grids operating at 50 cycles per second, ensuring seamless integration with regional power systems.

The LM2500 DLE Gas Turbine is an advanced power generation unit designed to deliver high efficiency while significantly reducing emissions. Utilizing cutting-edge Dry Low Emissions (DLE) technology, it precisely controls fuel and air mixing to minimize nitrogen oxide (NOx) emissions.

The LM2500 DLE utilizes a single-rotor gas generator with a 16-stage compressor and a two-stage high-pressure turbine, coupled with cutting-edge DLE combustion technology to reduce nitrogen oxide emissions. It supports dual-fuel operation on a wide variety of fuels, including natural gas, diesel, aviation fuel, LPG, and even hydrogen blends with concentrations ranging from 5% to 95%. The turbine’s open configuration allows for faster maintenance and quicker engine replacement, minimizing downtime.

Its key benefit is utilizing advanced aeroderivative gas turbine technology with dual-fuel Dry Low Emissions (DLE) capability, achieving ultra-low emissions of just 15 ppm NOx on gas fuel, combined with broad fuel flexibility—making it ideal for meeting strict environmental regulations while providing fast, reliable power for dynamic grid demands.

The 2-cup Fuel Nozzle is a precision-engineered component used in gas turbines, specifically in the oil and gas industry. Its primary function is to inject liquid fuel into the combustion chamber in a fine, atomized spray, allowing for optimal mixing with air and efficient ignition. This ensures stable combustion, better fuel efficiency, and reduced emissions—key performance factors in industrial turbine applications.

The “2-cup” design refers to the nozzle’s dual flow passages, which help balance fuel distribution across the combustion zone. This promotes more uniform flame stability and lowers the risk of hot spots that can cause thermal stress to the turbine hardware. The nozzle is typically used on “base” engines and is suited for continuous-duty operations.
